PLOW.

SPECIFICATION forming part of Letters Patent No. 618,202, dated January 24, 1899.

Application filed October 29,1898- Serial No. 694,930. (No model.)

To all whomit ntcty concern:

Be it known that we, ANDREW K. HANSON and LENARD EDWARD JOHNSON, citizens of the United States, residing at Valley City, in the county of Barnes and State of North Dakota, have invented certain new and useful Improvements in Flows; and we do declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to plows; and its object is to permit the landside and moldboard of a plow to be adjusted to the direction of the beam, in case the latter becomes warped or bent, without heating or straightening the plow-beam.

In many of the plows now in use the moldboard and landside, constituting the plow proper, are firmly and rigidly bolted to the beam,so that in case the beam becomes warped or bent the plow will out either too wide or too narrow and sometimes fail to do good work or 'work at all until the beam is straightened.

In the present invention one end of the beam is connected to a plate secured to the inside of the landside by a ball-and-socket joint, the socket being in the plate and the ball or half-ball being at the end of the beam, the one fitting the other. The ball is kept in its place in the socket by means of a rigid cross-bar on the end of the beam, through the ends of which pass bolts whose heads are flush with the outside of the landside, so that the nuts are on the ends of the bolts nearest to the moldboard. By loosening one nut and tightening the other a corresponding number of turns the point and heel of the plow may be moved sidewise with reference to the beam, so as to accommodate the direction of the plow to the direction of the beam in case the latter becomes warped or bent sidewise. The manner in which the moldboard is attached is also new and forms a part of this invention. Heretofore it has been customary to use braces firmly bolted at each end.

Our improvement consists in two pieces of metal, one secured to the beam and the other to the inside of the moldboard. The ends of these two pieces are linked together, so as to permit the moldboard to rock with reference to the beam,thereby allowing a relative movement of these parts when the landside is adjusted at the ball-and-socket joint.

The invention is principally for use in connection with gang and sulky plows, the beams of which are usually bent one or more times in the life of the plow, especially where used in breaking stony ground.

Our improvement will save the owner of a gang or sulky plow the expense and loss of time involved in one or more trips to the blacksmiths shop to have bent beams straightened.

In the accompanying drawings, Figure 1 is a perspective view with the moldboard partly broken away. Fig. 2 is a rear elevation. Fig. 3 is an elevation of the landside side of the plow. Fig. 4 is a bottom plan View, partly in section. Fig. 5 is a similar View showing the plow set at an angle to the beam. Fig. 6 is a detail showing the end of the beam.

Secured to the inside of the landside A is a plate B, in which is formed a semispherical socket Z). At the end of the curved beam O and at one side thereof is provided a semispherical head 0, adapted to fit into the socket b. A rigid cross-bar c is attached to the beam on the side opposite to the head or ball 0 and lies substantially parallel with the plate B. This bar may be channeled to save weight without losing stiffness. In each end of the bar is a hole to receive a bolt D, which passes through the plate B and the landside A, with its head flush with the outside of the landside. A nut d bears upon the cross-bar. It will be seen at once that by slacking off one of these nuts and tightening the-other the cross-bar and beam can be rocked in the socket so as to stand at a greater or less angle with the landside.

To relieve the ball-and-socket joint from too great strain and to adjust the draft of the plow, a tie-rod E is connected with the back of the beam and the landside. The rod has an eye at one end for a bolt e, attaching it to the landside. At the other end the rod is screw-threaded and runs through a hole in a bracket F, bolted to the beam. The hole is preferably countersunk on each side to permit the rod to swing sidewise when the beam is adjusted. Nuts a e on the tie-rod above and below the bracket enable the effective length of the rod to be altered within certain limits to bring the bottom of the landside to the proper plane with reference to the line of draft.

The upper edge of the moldboard G is supported against strain by a connection with the beam. This consists of a hinge-joint, so that it will not interfere with the adjustment of the beam. The joint is preferably made as follows: A strap H is bolted to the back of the moldboard, having its upper end worked into an eye h. The bolt I, which may be the one used to secure the bracket F to the beam, has its end also formed into an eye 2', which is interlinked with the eye h, as shown. This connection forms a rigid support for the moldboard, while permitting free movement of the beam with reference thereto when necessary. The lower rear end of the moldboard is sustained in fixed relation with the landside by means of a curved brace K.

Having thus described our invention, what we claim, and desire to secure by Letters Patcut, is,

1. In a plow, the combination with a landside, of a plate containing a ball-socket secured thereto, a beam having a rounded head on its end fitting said socket, and means for adjusting the beam laterally with reference to the landside, substantially as described.

2. In a plow, the combination with a landside, of a plate containing a ball-socket secured thereto, a beam having a rounded head on its end fitting said socket, a cross-bar on the beam, and bolts passing through the ends of the cross-bar and the landside, substantially as described.

3. In a plow, the combination with a landside, of a plate secured thereto and containing a semispherical socket, a curved beam having at its lower end a semispherical head projecting from one side and adapted to fit said socket, a cross-bar rigidlyconnected with the beam on the side opposite the head, and bolts passing through the ends of said crossbar and the landside, substantially as described.

4. In a plow, the combination with a landside, of a socketed plate attached thereto, a

beam having a rounded head to fit in said socket, a cross-bar and bolts for adjusting said beam, and a tie-rod adj ustably connected with the rear of the beam and the rear end of the landside, substantially as described.

5. In a plow, the combination with a landside, of a socketed plate attached thereto, a beam having a rounded head to fit in said socket, a cross-bar and bolts for adjusting said beam, a bracket secured to the rear end of the beam and having a countersunk hole through it;'a tie-rod attached to the rear end of the landside and passing through said hole, and adjusting-nuts on the tie-rod above and below the bracket, substantially as described.

6. In a plow, the combination with a landside, of a beam connected therewith by a balland-socket joint, a moldboard held in fixed relation to the landside, and a hinge-joint between the moldboard and the beam, substantially as described.

7. In a plow, the combination with a landside, of a beam connected therewith by a balland-socket joint, a vmoldboard, a strap attached thereto having an eye at its end, and an eye on the beam interlinked with the eye on the strap, substantially as described.

8. In a plow, the combination with a landside, of a beam connected therewith by a balland-socket joint, a moldboard, a strap attached thereto having an eye at its end, a tierod attached to the landside,a bracket through which the upper end of the tie-rod passes, and a bolt securing said bracket to the beam, said bolt having an eye interlinked with the eye on the strap, substantially as described.

9. In a plow, the combination with a landside A, of a plate B secured thereto and containing a socket b, a beam 0 having a head 0 fitting said socket, a cross-bar c on said beam, bolts D for adjusting said beam, a tie-rod E connecting the beam and the landside, nuts e e on said tie-rod, a bracket F secured to the beam having a countersunk hole, a moldboard G, and strap H secured thereto having an eye h, and a bolt I securing the bracket to the beam and having an eye 71 interlinked with the eye it, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
